Correct answer: C

Explanation

The correct answer is option 3 i.e. Resistance of a wire depends on the length and cross-section of the wire.

  • Resistance of a wire depends on the following factors-

  1. The length of the wire, resistance is directly proportional to the length of the wire.

  2. The cross-section of the wire, resistance is inversely proportional to the cross-section of the wire.

  3. The temperature of the wire, the resistance of wire is directly proportional to the temperature of the wire.

  4. The material of the wire (good conductors possess less resistance).
